Libretime-liquidsoap - 404 Client Error: Not Found for url

I get this libretime liquidsoap service error

In the Stream section I see the error:
Can not connect to the streaming server Problem with Liquidsoap...

In the Status section liquidsoap appear as not running.
I already tried to restart it: sudo systemctl restart libretime-liquidsoap but nothing changed

Looking in /var/log/libretime/liquidsoap.log I found many lines like this
2022-10-19 16:36:46.405 | ERROR | libretime_api_client._client:_request:78 - 404 Client Error: Not Found for url: http://stream.server.my/api/v2/info
If I visit http://stream.server.my/api/v2/info I get a json response:
station_name: "LibreTime"

libretime 3.0.0
Ubuntu server 20.04

I tried to search for an answer without success. Any idea?

The problem is solved modifying /etc/hosts file like this:
